If you're going to spend all day wine-tasting in Sonoma, you've got to start with a hearty meal to line your stomach and, er, mentally prepare. Thankfully, The Fremont Diner has your back. Head to the back patio where you can peruse the menu and order a mimosa until a table opens up (there will always be a wait, but it's worth it). Once you're seated, bring on the biscuits, chicken, waffles, and hot sauce.
